This book is the compilation of the teaching content being carried out in the Professionalism and Personal Development 1 (PPD1) module for the first 5 cohorts of pre-clinical students undergoing their new curriculum. This module book is compiled and published for the purpose of supplying a choice of companion and learning resources for PPD course across the academic years for the students and teachers to refer to. We hope with this module being introduced in the new curriculum, we shall produce not only excellent, and competent doctors professionally, but also doctors who can collaborate efficiently, are fair to themselves, cherished by their patients, and respected by their community.
